"These crazy kids with their magnets and their cholchacine."
You young Frankensteins need to cool out and burn one. Be patient. Remember that the plant is a living thing. Give it the right amount of light, ferilizer, water, and air flow, and it will be healthy. Healthy plants grow faster and produce higher yields.
You want increased potentcy? Buy better seeds. There is nothing else you have any control over that is more important than genetics. All the botany skills in the world won't make Kansas Ditch Weed into Ganga.
The earth is a magnet. North on top, and South on the bottom. This provides probably all the magneting force any plant needs.
You want healthier seedlings? Use a little miracal grow in your germanation water. Yery weak solution, about half strength of reccomended weekly feeding strength.
If you want to know if seeds do better treated with a magnetic field, you have to take a random sample of seeds from the same plant, and sprout fifty with the magnets, and fifty without, and compare. Anything less will just add to all the misinfornmation out there. And remember, when a scientist says there was "significant" effect, they just mean it was measurable. It doesn't mean it will even shave a day off of your growth cycle, or increase your yield to the point where it returns your investment in machinery.
Be patient. Buy smoke if you have to till harvest time, but be patient.
On average, most growers harvest 1-2 weeks before the right time. When you think they are ready, give them two more weeks and no water for the last week. Harvest after the shade leaves wilt. The buds will react to the dry conditions by producing more protective resins to slow moisture loss through transpiration.
Oh yeah, sorry. I'm a former nursery manager and botinist. My first indoor crop was in the early eighties with a 1000 watt super halide in a 10 by 12 foot room. Sea of green, Hawaiian stock. Second crop was something almost nobody had ever had ever heard of: Canabis Indica.
I go that far back, and know what I'm talking about.
